Like an ordinary text field, a password field fires anĪction event when the user indicates that text entry is complete, for example by pressing the Enter button.
As another security precaution, a password field stores its value as an array of characters, rather than as a string. Instead, the field displays a character different from the one typed, such as an asterisk '*'. For security reasons, a password field does not show the characters that the user types. Now delete your default "index.jsp" file and create a new "index.html" file and write the following code for it.Ĭreate a new servlet file named "Filter.java" and write the following code for it.JPasswordField class, a subclass of JTextField, provides specialized text fields for password entry. Type your project name as UserAuthenticationDemo.Ĭlick on "Next" then select your Java version and server details as in the following:
Select "Java web" -> "Web application" as in the following: Use the following procedure to create this app. If the user logs in with an admin password then they enter our website else they are redirected to the login page. In this example we are creating a web page in which we create an admin control for login.
We use a security policy by providing user-authentication to distinguish the users from others. There are multiple users that can visit our website to find which one was "admin" and which one was "manager" and so on. It is sometimes called a security policy domain or security domain, it is a scope over which an application server defines and enforces a common security policy. The NetBeans IDE is used for the sample application. This article explains user authentication using a servlet in Java.
